A Chilean judge has ruled that former Peruvian President Alberto Fujimori should not be extradited to Peru, where he faces corruption and human rights charges.

The judge Wednesday rejected the extradition request made by the Peruvian government.

Fujimori has been under house arrest in Chile awaiting the court's ruling.

The former president allegedly sanctioned the killing of 25 people by paramilitary squads during his presidency, which ended in 2000. After his government collapsed, he spent five years in exile in Japan before moving to Chile in 2005.

Fujimori, who has dual citizenship, recently announced that he intends to run in this month's Japanese Senate elections.
